Bug 539356. Make PruneDisplayListForExtraPage prune print preview properly. r=mattwoodrow PruneDisplayListForExtraPage wasn't pruning properly in print preview. It was pruning to the RootReferenceFrame, which is per-page when printing normally, but is the ancestor of all pages in print preview, so it wasn't doing anything in print preview. So, pass in the nsPageFrame we want to prune to. This prevents bogus entirely-clipped-out display items appearing in the display list for the page.

/**
 * This is an implementation of NTLM authentication that does single-signon
 * by obtaining the user's Unix username, parsing it into DOMAIN\name format,
 * and then asking Samba's ntlm_auth tool to do the authentication for us
 * using the user's password cached in winbindd, if available. If the
 * password is not available then this component fails to instantiate so
 * nsHttpNTLMAuth will fall back to a different NTLM implementation.
 * NOTE: at time of writing, this requires patches to be added to the stock
 * Samba winbindd and ntlm_auth!
